Title: System for multichannel processing of redundant wellbore sensor
Inventor: COOPE DANIEL FREDERICK
IPC: E21B47/12
Filed: 1985-03-12
Abstract: In order to provide enhanced reliability in the measurement of downhole parameters within a borehole, each downhole parameter is sensed by a pair of detectors 131, 132 and a stream of datapoints representative thereof is generated. Each stream of datapoints is analysed by a processing system 135 relative to the expected statistical norms and physical parameters known to be associated with the characteristics of the detectors 131, 132, to determine whether the datapoints are within the acceptable ranges and parameters. A flag is generated for each stream of datapoints found to be outside the ranges and parameters. The flags are recorded by a recorder 137 together with the streams of datapoints found to be within the acceptable ranges and parameters. <IMAGE>
Patent GB-2179129-A (GB)
Title: Apparatus for cooling and dispensing drinks
Inventor: PAXMAN NEIL ERIC
IPC: B67D1/08
Filed: 1985-06-18
Abstract: Apparatus for cooling and dispensing wine or beer comprises a refrigeration unit 2 and two cooling and dispensing units 3. The refrigeration unit 2 comprises an evaporator tank 4, and a compressor 5 with condenser 6 under thermostatic control. The tank 4 is of modest capacity, and in it water is cooled by the refrigerant. The water flows via lines 10 and 11 to and from the units 3, which are connected in series via a line 35. The water cools the wine or beer passing through coils within the units 3. Two thermostats 19 are arranged in parallel, and respond to the temperatures within the units 3, to control operation of a common pump 9, which causes the flow of coolant water through the lines 10 and 11. There is a relatively large contact surface area between the refrigerant coils and water in the tank 4, and between the wine or beer coils and water in the units 3. There is a relatively small amount of water in the entire circuit between the tank 4 and the units 3. Therefore, the system acts with very low thermal inertia, and heat may be transferred quickly between the wine or beer and the refrigerant, via the coolant water. <IMAGE>

Title: Improvements in or relating to tachograph charts
Inventor: BROCKBANK R G
IPC: G07C5/12
Filed: 1985-07-01
Abstract: A tachograph chart has an area 24 to receive a record of time spent driving, resting or engaged in garage or other repair work, the area 24 being divided into two annular bands 24a and 24b respectively intended to receive a trace when the chart is used in conjunction with a tachograph in which a manual operation is necessary by the driver in order to indicate a change from one category of use to another, and to receive a trace when the chart is used in conjunction with a tachograph in which a change from one category of use to another is registered automatically, e.g. by using appropriate sensors, the position or form of the trace in each case indicating the particular category of use concerned. Symbols 28, 32 aid the interpretation of the manual and automatic tracers respectively. Consequently the same design of chart can be used for different types of tachograph, thereby reducing printing and stocking costs. <IMAGE>

Title: Vibration wave motor control
Inventor: SUZUKI NOBUYUKI
IPC: H02N2/14
Filed: 1986-10-07
Abstract: A travelling vibration wave motor has a stator (1) and a rotor (not shown) in functional contact therewith, the stator (1) being excited by a periodic drive signal applied to electrodes (1-1, 1-2) of piezoelectric, magnetostrictive or electrostrictive transducers so as to generate a travelling vibration wave in the stator. A signal representing the drive status of the vibration wave motor is produced (eg. by an electrode 1-3, any phase difference between the status signal and the drive signal is detected and the frequency of the drive signal is controlled e.g. by a phase-locked loop (3, 4, 5) such that the phase difference is equal to a predetermined constant e.g. 90 DEG . The motor is thus driven at resonance even though the motor load or an environmental condition may change. Details of the phase-locked loop are described. <IMAGE>
